Title: Oil separator for IC engine - removes oil mist from intake air and has heated wall to vaporise part of oil
Inventor: BAUMGAERTNER REINHARD DR
IPC: F01M11/08
Filed: 1991-06-15
Abstract: Intake air is deflected by baffles (2) onto the walls of the separator (1). The separator (1) can be located in a section of pipe where the temp. of the air passing through is so high that the base and flux constituents of the oil are vapourised, or the temp. of the separator walls themselves is high enough to vapourise the oil when it comes into contact with them - minimum 160 deg.C for multigrade and 190 deg.C for single grade oils. The remaining oil constituents form an adhesive coating on the separator wall. The separator (1) is best positioned in the intake pipe (3) upstream of the charge cooler (5). USE/ADVANTAGE - A simple and cheap, but very effective, method of removing oil particles from intake air of turbocharged IC engine. Compact, easy to clean and dismantle.

Title: Selective thinning of particle collections in aerosols - diverting partial flow from accelerated flow, filtering it and feeding it back before acceleration stage
Inventor: KOCH WOLFGANG DIPL PHYS DR RER
IPC: G01N15/08
Filed: 1992-06-05
Abstract: The thinning method involves accelerating a vol. flow carrying a particle collection, an aerosol, and a partial flow guided at an angle w.r.t. the acceleration direction out of the accelerated flow.

Patent DE-4305123-A1 (DE)
Title: Throttle valve arrangement
Inventor: GERARDS HANS
IPC: F02D9/10
Filed: 1993-02-19
Abstract: An intolerable leakage or actuating stiffness persists in known throttle valve arrangements. By contrast, the new arrangement has the characteristic features that the bearing sleeves are radially displaceable inside a housing recess and that, on initial closing of the throttle valve after assembly, dimensional variations between the stop faces and the throttle valve shaft bearing or the bores are compensated for by positional adjustment or radial displacement of the bearing sleeves. The new arrangement affords greater leak-tightness whilst precluding any actuating stiffness and is suitable for internal combustion engines.

As far as possible the dimensions of the UIC replacement parts are adopted for the upper support area of the chain link (1), the upper chain-link block (4) and the upper spring bolt (3). The diameter of the lower support area including chain-link block (5) and/or the diameter of the lower spring bolt (3) are increased to such an extent that the transverse and longitudinal damping values required for high travel speed and large axial travel masses are achieved. The support area of the chain-link block (4, 5) is provided with a depression or the support area of the spring bolt (3) is provided with a flattened portion, the said depression or flattened portion contributing to increasing the longitudinal damping. In order to increase the transverse spring constant of the wheel set guidance, the chain links (1) can be arranged spread out apart from one another in the transverse direction of the wagon. The chain-link suspension according to the invention is provided for the running gear of rail vehicles and is particularly suitable for retrofitting in UIC standard wagons. <IMAGE>
